CONCRETE consrnucrrom To all whom it may concern:

Be it known that I, ERNST STEUDE, a citizen of the United States, residing. at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in. Concrete Constructions, of which the following is a specificatlon. Y e

My invention relates to a reinforced concrete construction, and my invention consists of the novel features herein shown, described and claimed- An object of my invention is to make a leinforced concrete construction which can be built up without the use of molds.

A further object of my invention is to make concrete blocks which may be set up and. fastened together with links and pins. A further object of my invention is to make a reinforcing frame so that the concrete may be plastered on to the frame instead ofbeing molded as heretofore.

A further object of my invention is to make a reinforced concrete construction by setting up a framework of concrete blocks applylngreinforeing rods and then plastering the concrete on to the reinforcing rods without the use of molds onthe job.

Figure 1 is a perspective of a building showing a reinforced concrete construction embodying the principles of my invention.

Fig. 2 is a fragmentary horizontal sectional detail showing the concrete blocks held together by links and pins set in cement and showing the reinforcing rods and the concrete built on to the rods to fill up the spaces between the blocks.

Fig. 3 is a fragmentary sectional elevation further illustrating the construction shown in Fig. 2.

Fig. 4 is a fragmentary detail perspective showing the roof construction.

The horizontal plates 1 and '2 are constructed of concrete or cement blocks 3 and 4 and the vertical columns 5 are constructed of concrete or cement blocks 6. The block 3 has a vertical opening 7 through one end and a horizontal recess 8 extending from the end face of the other end, and a pin hole 9 ex tending horizontally transversely of the re oess 8. The block 4 has recesses 10 and 11 extending from its end faces and pin holes 12 and 13 extending transversely of the recesses 10 and 11. The plate 1 has a block 3 at each end and a plurality of blocks 4 between the blocks 3. Links 14 are placed Specification of Letters iatent.

Application filed November 25, 1918. Serial No. 264,045.

in the recesses 8 and 10 and as the blocks are brought together the interstices are with soft cement, and pins 15 and 16 are inserted through the pin holes 9 and 12 and through the links 14 and the soft cement, so that when the cement hardens the blocks are rigidly secured together. In a like manner, the row of blocks 4 are secured together. ,Vertical openings 17 are formed through the centers of the blocks 4 and at the proper time p the reinforcin rods 18 are inserted into these openings 1 and the spaces around the. blocks in the openings are filled with soft cement, so that the rods are rigidly fixed in the blocks when the cement sets.

The blocks 6 are preferably mounted end to end in vertical planes and have link recesses in their ends for securing the blocks 6 to the blocks 3, and for securing the blocks 6 together. The link 19 and the pins 20 and 21 secure the lower block 6- to the block 3, there being soft cement inserted as the parts are placed together, and in a like manner, the link 22 and pins 23 and 24 secure the second block 6 to the lower block 6. The link 25 and pins 26 and 27 secure the block 3 of the plate 2 to the second block 6, and the link 28, the pin 27 andthe. pin 29 secure the third block 6 to the block 3 of the plate 2. The plate 2 is, or may be, identical in construction with the plate 1, and any desired number of plates may be used to produce a wall frame of the desired height. The reinforcing rods 18 extending upwardly through the plate 2 are cemented in place. The blocks of the plate 2 may be held in line in various ways until the cement hardens.

In order to fill the spaces between the plates 1 and 2 and between the vertical columns 5 without building a mold upon the job, I make a soft tube 30 of cloth or canvas, fill the tube with soft cement and weave the tube back and forth from the plate'l upon the reinforcing rods 18 to the desired height of the panel, and then build the plate 2 upon this woven work. After the framework has been completed, I plaster the cement or finishing material upon both sides of the woven work to give the wall the desired finish. The woven work comprising the tube 30 and the reinforcing rods 18 will sustain the plaster, concrete or cement and the wall may be finished without any molds.

After the plaster has been applied to the fabric of the tube and harden and produce a solid reinforced wall whichiis as good, or better than a wall formed in a mold.

In order to produce the roof 31 in the same way, the upper ends 32 of the vertical columns are beveled to give the proper slant to the roof, and the blocks 33 and 34: are

secured to these upper blocks 32 by links and pins, and then the longitudinal lines of blocks 35 and 36 are applied, the reinforcing rods 37 are incorporated into the blocks, the tube 38 of cement is woven into the reinforcing rods and the plaster 39 applied to the inner and outer faces to finish the roof as desired.

Thus I have invented a process by which a reinforced concrete construction can be erected without the use of molds and casting boxed upon the job.

Heretofore, it has been the practice in building a concrete structure upon an isolated lot to haul lumber on to the lot, built the wall molds in place, pour the concrete into the blocks, allow the concrete to set and then to tear down the molds and haul the lumber away, and by my process, I have avoided the use and expense of the lumber.

By my process, I produce a reinforced concrete construction which may be built up upon an isolated lot and consisting of plates built of blocks bonded and cemented together, vertical columns built of blocks bonded and cemented together producing open panels, reinforcing rods inserted and cemented into place, a filler of soft bonding material woven into the reinforcing rods, and plaster applied to the filler to give the structure the desired finish.

In a companion application I have shown,

described and claimed the specific block con- 2. The process of producing reinforced I concrete work which consists of building a vertical framework having vertical openings, placing reinforcing rods vertically in the openings, weaving a bonding material horizontally back and forth around the reinforcing rods to a desired height, said bonding material comprising a fabric tube filled with soft cement, and the woven work extending to a desired height, then placing plates upon the woven work and applying plaster to the sides of the woven work.

In testimony whereof I have signed my name to this specification.
